実験手順

(6-Bromopyridin-2-yl)acetonitrile (50 mg, 0.25 mmol) was taken up in methanol (2 mL) and 1 N aqueous sodium hydroxide (2 ml, 2 mmol) was added. The reaction was heated to 80° C. overnight. Upon completion, the reaction was cooled to ambient temperature, diluted with ethyl acetate (15 mL) and water (15 mL), and the layers were separated. The aqueous layer was acidified with 2N aqueous hydrochloric acid and extracted with ethyl acetate. The organic layer was dried over magnesium sulfate, filtered, and concentrated in vacuo to afford the title compound which was used without further purification.
